Problems solved by technology

[0005] At present, the above-mentioned patents have certain deficiencies in the actual operation process: in the process of mold opening or demoulding, the above two existing technologies can indeed improve the efficiency of mold opening, but the first patent document uses a manual method. It can realize the demoulding of a piece of lens, which is labor-intensive, low in efficiency, and high in labor costs; the second patent document uses a manual control eccentric wheel to drive the pressure head to extrude the mold to achieve demoulding. This device can adjust the relationship between the pressure head and the limit mechanism. distance, to realize the release of lenses of different sizes
This method adopts a manual method, which can only open a mold for a single lens each time, which is labor-intensive and costly

Embodiment 1

[0028] Embodiment 1: When working, the lens mold is placed on the positioning plate 32. The long-hole-shaped positioning hole on the positioning plate 32 positions the center of the lens mold and can move along the hole according to the diameter of the mold. One end of the lens mold is connected to the limit device 4 contact, the pressure head drive plate 12 is installed on the horizontal linear motion support 11 and the linear slide 13, the linear slide 13 drives the motor to move the lateral drive device 1 laterally along the track of the horizontal linear motion support 11, and the pressure head drive plate The indenter 14 of 12 squeezes the mould, and the distance between the indenter 14 and the limit device 4 is adjusted by the linear slide 13 to meet the mold opening of molds with different diameters, and the longitudinal driving device 36 is fixed on the second bracket 22 through the bottom fixing plate 37 , the longitudinal driving device 36 is combined with the longitu...

Embodiment 2

[0029]Embodiment 2: When working, the lateral drive device 1 moves laterally along the track of the horizontal linear motion support 11, the positioning plate 32 moves up and down along the track of the longitudinal linear motion support 31, and the pressure head 14 is horizontally opposite to the limit device 4 Position, the positioning hole on the positioning plate 32 and the arc center line of the limiting device 4 are in a horizontal relative position, and the limiting device 4 and the pressure head can be changed according to actual needs under the condition that the above motion trajectory and relative position are kept unchanged. 14. The number of positioning plates 32 enables simultaneous mold opening of multiple molds, and the power and thrust of the linear slide table 13 and the longitudinal drive device 36 need to be re-matched for multiple mold opening.

Abstract

The invention discloses an optical lens automatic mold opening device which comprises a transverse driving device, an overall support, a positioning and longitudinal driving device and a limiting device. A press head can transversely move through the transverse driving device, so that opening of molds with different diameters is realized. A positioning plate can longitudinally move through the positioning and longitudinal driving device, so that opening of molds with different thicknesses is realized. A positioning hole in the positioning plate is in a long hole shape so that center positioning of the molds can be achieved, and the molds can move along the hole. The limiting end of the limiting device is in a circular arc shape so that center positioning of the molds can be realized. The multiple optical lens automatic mold opening devices can also be used in parallel. In conclusion, the problems in the actual operation process are solved, mold opening of the molds with different sizes can be accomplished through the cooperative use of the transverse driving device and the positioning and longitudinal driving device, the optical lens automatic mold opening device is not limited by the diameters and the thicknesses of the lens molds, full-automatic mold opening is achieved, and manual intervention is not needed in the mold opening process.

Description

technical field [0001] The invention relates to a mold opening device, in particular to an automatic mold opening device for optical lenses. Background technique [0002] In the spectacle lens industry, manual mold opening is generally used, which has low mold opening efficiency and high labor costs. When taking out the lens, the upper and lower molds are first separated. After detachment, the lens adheres to the curved surface of the upper mold. Cut off the remaining material, then heat the upper mold, and use the lens taking mechanism to take out the lens. The existing equipment uses semi-automatic tooling to connect the above processes in series, especially the method of manually taking out the lens. Manually put the upper mold containing the lens into the semi-automatic tooling, then squeeze the upper mold, and finally take out the lens with a suction cup. The productivity of the existing equipment is very low and cannot meet the needs of automated production. [0003]...
